The remote host is affected by the vulnerability described in GLSA-202007-18 (QtNetwork: Denial of service)

    A flaw was discovered in QtNetwork&rsquo;s handling of OpenSSL protocol       errors.
  Impact :

    An attacker could cause a possible Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2020:4690 advisory.

  - Qt through 5.14 allows an exponential XML entity expansion attack via a crafted SVG document that is     mishandled in QXmlStreamReader, a related issue to CVE-2003-1564. (CVE-2015-9541)

  - In Qt through 5.14.1, the WebSocket implementation accepts up to 2GB for frames and 2GB for messages.
    Smaller limits cannot be configured. This makes it easier for attackers to cause a denial of service     (memory consumption). (CVE-2018-21035)

  - Out of bounds write in Intel(R) PROSet/Wireless WiFi products on Windows 10 may allow an authenticated     user to potentially enable denial of service via local access. (CVE-2020-0569)

  - Uncontrolled search path in the QT Library before 5.14.0, 5.12.7 and 5.9.10 may allow an authenticated     user to potentially enable elevation of privilege via local access. (CVE-2020-0570)

  - Qt 5.12.2 through 5.14.2, as used in unofficial builds of Mumble 1.3.0 and other products, mishandles     OpenSSL's error queue, which can cause a denial of service to QSslSocket users. Because errors leak in     unrelated TLS sessions, an unrelated session may be disconnected when any handshake fails. (Mumble 1.3.1     is not affected, regardless of the Qt version.) (CVE-2020-13962)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Mumble 1.3.2. ===

Client

  - Fixed: Overlay not starting (#4282)

Server

  - Fixed: keychain-error on macOS for custom certificates     (#4345)

Known issues

  - Overlay blocked by BattleEye. A request to whitelist it     has been made.

  - Overlay blocked by CS:GO Trusted Mode

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2020:4690 advisory.

  - qt: XML entity expansion vulnerability (CVE-2015-9541)

  - qt5-qtwebsockets: websocket implementation allows only limited size for frames and messages therefore     attacker can cause DOS (CVE-2018-21035)

  - qt: files placed by attacker can influence the working directory and lead to malicious code execution     (CVE-2020-0569, CVE-2020-0570)

  - qt5: incorrectly calls SSL_shutdown() in OpenSSL mid-handshake causing denial of service in TLS     applications (CVE-2020-13962)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update for libqt5-qtbase fixes the following issues :

Fixed a possible crash in certificate parsing.

Fixed a DoS in QSslSocket (bsc#1172726, CVE-2020-13962).

Added support for PostgreSQL 12 (bsc#1173758).
